Dwarf Hairgrass: Eleocharis parvula

Dwarf Hairgrass

Dwarf Hairgrass (Eleocharis parvula) is a quintessential aquatic plant celebrated for its fine, grass-like appearance that adds a lush, verdant aesthetic to aquascapes. This carpet-forming species thrives well in both high-tech and low-tech setups, making it a versatile choice for aquarists at any skill level. Its slender, bright green blades can grow up to 10 cm in height, creating a soft, flowing appearance that beautifully complements larger plants and creates a naturalistic underwater landscape.

Care Guide

To maintain Dwarf Hairgrass, it is essential to replicate its native habitat conditions. Here are detailed maintenance instructions:

1. Lighting: Provide moderate to high lighting, ideally above 2 watts per gallon. It promotes denser growth and a more vibrant green color.
2. Substrate: Use a nutrient-rich substrate to encourage robust root development. Fine gravel or a specialized aquatic soil works best.
3. Trimming: Regular trimming is necessary to prevent the plant from becoming too tall and sparse. Trim back the growth regularly to maintain a neat carpet appearance and stimulate new growth.
4. Water Parameters: Optimal growth occurs in slightly acidic to neutral pH (6.0 - 7.5) with temperatures ranging from 20°C to 26°C (68°F to 78°F).
5. Propagation: Dwarf Hairgrass can be propagated by cutting and replanting sections of the rhizome or by division.

Nutrient Requirements

1. Light: Moderate to high lighting is critical for optimal growth; low light can result in leggy and sparse growth patterns.
2. CO2: Supplemental CO2 injection significantly enhances growth rates and overall plant health but is not strictly necessary in low-tech setups.
3. Fertilization: Regular dosing of liquid fertilizers or root tabs can help fulfill the nutrient needs of Dwarf Hairgrass, ensuring lush green growth and health.

Natural Biomes

Dwarf Hairgrass is commonly found in several natural biomes, including:

• The Amazon Basin, characterized by its warm waters and rich biodiversity, which provide optimal growth conditions.
• The Mekong Delta, known for its nutrient-rich waters and diverse aquatic plant life.
• The Orinoco, which showcases the plant’s adaptability in varying water conditions.

Livestock Compatibility

Dwarf Hairgrass is highly compatible with various aquatic life, enriching the ecosystem of your tank. Ideal companions include small schooling fish like Tetras and Danios, as well as peaceful shrimp species such as Cherry Shrimp and Amano Shrimp. These inhabitants not only coexist well with Dwarf Hairgrass but also contribute to the overall health of the aquatic environment, maintaining algae levels and promoting a balanced ecosystem.
